Questions tagged [open-source]

Software required to be open-source. This is not to be confused with "gratis" software, which is free of cost. Open-source, sometimes called "free" or "libre" software, has the original source code freely available to be viewed, redistributed and modified. Please don't use this as the only tag on a question; add tags which indicate the functionality as well.
